Hi All

I want to export mesh created in ICEMCFD to Fluent 6.2, both structured and unstructured mesh. can anyone help me how to export mesh to fluent, what is the process to be followed to export mesh to fluent. i am using ICEMCFD 11.

Thank you

in the output tab -> select the solver as "fluent_v6" and the there is icon at the end "write input" using that you can export the mesh file.

use the same procedure for both unstructured and structured, just you need to have unstructured mesh and multi block mesh respectively in ICEM

Thank you rohit for you reply.

i tried with your solution what you have suggested, but the mesh is not been read in fluent. an error is being displayed as

Error: FLUENT received fatal signal (ACCESS_VIOLATION)

1. Note exact events leading to error.

2. Save case/data under new name.

3. Exit program and restart to continue.

4. Report error to your distributor. Error Object: ()

I AM NOT ABLE TO UNDERSTAND WHAT IS THE PROBLEM.

CAN YOU HELP ME OUT

THANK YOU.

HI Rohit.

I was actually able to export the unstructured mesh(tetra) But was ot able to export structured. i tried with converting the structured to unstructured and then exporting, but the error was bisplayed in the fluent window and also tried to convert into multiblock,but in the write input option was not able to convert it into msh file.

It would very helpfull if u could help me out regarding the export of structured mesh because i am basically working on structured meshing and does not rely on unstructured.

Thank You

Hi jeevan,

Before you export the mesh, did you check the mesh by using "grid check". i mean whether your mesh pass the grid check?

and coming to the structured mesh, i am not a user of fluent but when i select the fluent_v6 as my solver it says that the solver accepts only unstructured format so whether fluent has structured mesh solving capability? if yes then may be u need to put this question in fluent forum as i guess they can help you in which format solver accepts the mesh

thank you rohit.

no i have not checked the unstructed mesh which was converted from structured, i will check and will try importing.

i will post the question in the fluent forum regarding structured mesh export.

Thank you. regards
